SHAFTlNG-HANGER.

SPECIFICATION forming part of Letters Patent No. 429,723, dated June 10, 1890.

Application filed January 13, 1890. Serial No. 336,723. (No model.)

T0 all whom it may concern;

Be it known that I, MELVILLE D. HEMEN- WAY, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented a new and useful Shafting-I-Ianger, of which the following is a specification.

My invention relates to hangers for shafting; and its mechanism is illustrated in the accompanying drawing, in which a spindleframe A supports the movable spindle B and the bifurcated shaft-bearing frame C. The shaft-bearing frame C can be raised to any elevation Within the length of the spindle B and held securely at the desired elevation by means of the collar D, set-screw F.,and checknut F.

The collar D is not fixed to the frame A, but has the freedom of the recess G, and the spindle B is thus permitted to oscillate about a vertical axis within the spindle-bearings H.

The bifurcated shaft-bearing` frame C is at all times iirmly fixed to the spindle B and oscillates with it.

The shaft I is held in the shaft-bearing J, which is provided with trunnions T, which are supported upon the pointed screw-pivots K, and the shaft-bearin g oscillates freely upon the screw-pivots about a horizontal axis.

The combination of the oscillating shaftbearing .I with the oscillating spindle B furnishes a constant and automatic adjustment to any irregular motion of shafting arising from whatever cause.

The spindleframe A is described herein and represented in the drawing as a standard; but it can be used either as a standard, hanger, or bracket, and can be thus attached to floor, overhead, or wall timbers, and in all positions in which it may be placed the axis of oscillation of the spindle B is at right angles to that of the shaft-bearing J.

My invention is adapted to any kind of shafting; but it is particularly adapted to light and flexible shaftin' g, and to cases where electric motors, spring-motors, or small waterwheels are used, requiring economy of power MELVILLE D. I'IEMENVVAY.
